I took a working memory test every day for the past 100 days. On half the days, I had drunk 0.5 UK units of alcohol before starting. On the other days, I took a placebo. All monitored and prepared by a friend. So it was a single-blind test.

I completed a memory test prepared by said friend - very similar to brain workshop if you've ever played that.

The first 40 days had rapid progress in the test and were eliminated from the final results. For the remaining 60 days, my average score(variance) without alcohol was 7.4(0.4) and was 8.0(1.2) with.

Alcohol improved my working memory.

Haha, good job man. Should've tested for everything between sober and blind drunk though.

Do the parentheses give errors? If so then you've drawn the wrong conclusion.

[Anonymous No.2988227]

You obviously need to relax.

[e !!EBH6rAQHwGN No.2988230]

>>2988223
The brackets give the variance. If you want to use the standard deviation for errors (which is pretty common), take the square root of the number in the brackets.

>>2988225
That would be good, but I would need a lot more than 100 days.

[Anonymous No.2988238]

How did you take an alcohol placebo?

Then your results are not statistically significant. Continue testing.

It's not that hard to find a similarly tasting drink.

[Anonymous No.2988251]

>>2988219

That's a known side-effect of alcohol.

IF you drink only a little bit, your reactions will get faster, you can run longer etc. etc..

Glad I'm not the only one who hates Heineken. Seriously, fuck you Holland.

It was a weird vinegary mixture.

>>2988243
You're right that it's too early to draw absolute conclusions. If this were a scientific paper, I'd have to say: "Preliminary results suggest that 0.5 UK units of alcohol increases ability on working memory tasks, but further research is required."

>>2988251
Well, I don't know of any working memory tests, however it does complement this:

Dutchman here. Heineken tastes like sewer water. It's a cheap commercial beer. If you want some good tasting beer, get a local one. Fuck, even Bavaria is better.

No you can't if this were a scientific paper your results would not be significantly differend and thus no conclusions can be drawn.

Hoegaarden and Kriek are pretty good. Don't be so harsh.

Can't say I remember any Dutch beers. All I remember from last time I was in the Netherlands was how expensive beer was. And how stoned I was.

Unless it's totally different from the beer sold in the UK by the same name, you can take that shit and fuck off back to Weedland.

I'm just saying when you look at belgium style wheat beers. The dutch do them better than the belgians.

[Anonymous No.2988516]

Assuming that your result is valid, I think the most plausible explanation for the small difference is cerebral vasodilation. Alcohol causes blood vessels to temporarily relax and dilate, but once the alcohol leaves your system, they respond to this change by contracting past their normal equilibrium, before eventually relaxing again to the resting diameter.

If you took the test somewhat later, you would probably score worse than average on the alcohol days rather than better, reflecting the subsequent period of constriction.

Also, I wasn't talking about the Dutch and Belgian beers, but the countries. An interesting interview, of Frank Zappa of all people, where Frank talks about the difference between Americans and Europeans: you're hard pressed to find someone from Europe that calls themselves a European. They're always French, German, British, etc.

TL;DR: Europeans are stupidly divisive about shit that doesn't matter.

[Anonymous No.2988583]

>>2988575
That's because EUROPE ISN'T A COUNTRY.

You'll be hard pressed to find somebody in the US who calls themselves "North American" and groups themselves with Canada and Mexico.

Asia isn't a country, but there's still a lot of Asian Pride, as well as individual nationalism.

Also, in my mind the EU is almost like a level of government above the countries, like a federation but obviously much looser. Haven't looked into it much, because that's Economics, and Economics is for faggots.

I'm waiting for my boyfriend to bring it up.

Also, US citizens DO call themselves Americans, but that all depends on interpretation as to if it applies here.

No shit, because their country is called America. They don't refer to themselves by continent.

Just an interesting thing I'd noticed, like, arguing about the difference in beer quality between two countres, when those countries are so close and tiny they'd both fit in South Carolina with room to spare.

The EU is an economic alliance, nothing more. It is not an international government.

The Asian pride you see is more of an ethnic "Azn" pride than it is pride to be in the continent of Asia. Do Russians have Asian pride? Do Indians have Asian pride? Do Middle Eastern people have Asian pride? Because they're all in fucking Asia.

[Anonymous No.2988633]

Amendment: Russia is HALF in Asia. I should have specified Eastern Russians.

[Anonymous No.2988641]

>>2988630

Most of the population of Russia is on the European side of the country, India is its own subcontinent and the Middle East is largely shielded by that subcontinent.

And how do you delineate AZN pride from pride in being from Asia, exactly?

[Anonymous No.2988645]

for the first hundred years of so of the united states, the citizens referred to themselves as citizens of their states. even now displaced citizens proudly claim their roots.
